Graeme is it possible to get a definitive statement on what these engines produce? The talk on the EPEC page was that they were 9hp, but you are saying 7.1hp. As stated previously anything over 7.5 means they are an irrelevance for MSA Clubmans drivers.
This from the Pro Extreme FB page infers they would be over 7.5hp: "Pro Extreme 31 December 2013 .....the motors are 25% more power than a GX160 SP, they are all dynoed and sealed to be a level playing field......after the meeting the motors are for sale."
Given my old T1s dyno at just under 7 with Kelvins timing tool applied, a rise of 25% plus whatever difference an SP gives is going to be too high for Clubmans MSA.
